Connections
Follow these steps to connect speakers in series.
1. Connect the first speaker’s positive terminal to
the other speaker’s negative terminal.
2. Connect the first speaker’s negative terminal to
the amplifier’s COM terminal.
3. Connect the other speaker’s positive terminal
to the amplifier’s terminal (4
, 8 , or 16 )
that matches the total speaker impedance.

Speakers are connected in parallel when all
speakers’ negative terminals are connected
together and all their positive terminals are
connected together.
Determine the total speaker impedance of
speakers you want to connect in parallel by
dividing the impedance of one speaker by the
number of speakers.
For example: If connecting two 8-ohm
speakers in parallel, divide 8 (one speaker’s
impedance) by 2 (number of speakers). Your
total speaker impedance is 4.
